To all whom it may concern: 1 v i 1 Be it known that I, CHARLES W.DARROW,

of Glenwood Springs, in the county .ofGarfield and State of certain newand useful Improvements in Flushing Devices; and I do hereby declare thefollowing to be a'full, clear, and exact de scription of the invention,such as will en able others skilled in the art to which it ap pertainstomake and use the same.

The primary object of this invention is to produce an extremely simpleand inexpensive flushing device, which will be free from noise, capableof being started and stopped without-shock or wire drawing, and whichwill be composed of but few parts. V

In the accompanying drawings, Figure 1 is a longitudinal sectional view.Fig. 2 is an end view, partly in section, showing the control valve inthe position it occupies when the main valveis seated. Fig. 8 is a viewsomewhat similar to Fig. 2, showing the control-valve moved to allow themain valve to be unseated. 1

Referring to the drawings, 1 designates a casing; 2 the inlet; 3 theoutlet; and 4 a bypass leading from the inlet to the pressure chamber ofthe casing. Communication between. inlet 2 and outlet 3 is controlled bya main valve 5, which is shown as having a cylindrical body portionfitting within the pressure chamber, and as having a tapered portion 6which, when it engages its two seats, will cut off thefiow ofWater,'said tapered portion 6 terminating in a lug 7, as'locatedcentrally of lVhen the valve is opened of this lug is within the end ofthe inlet opening the inlet opening. the lower portion plane of theupper so that the outflow causing a damming of the water at this pointand a'consequent greater force or pressure through the bypass to theupper side of the valve, thus insuring closing of the valve against theinlet pressure. This valve 5 is free to turn on its axis while movinglongitudinally toward and away from its seats.

The entrance of the water through bypass 4 into the pressure chamber iscontrolled by a swinging valve 8, which is pivoted at the axis of casing1 on a stud 9 extended through end cap 10, an operating handle 12 beingsecured to said stud. I have shown packing 13 surrounding the inner endof the stud and bearing against'the face of rnusnnve nnvicn.

cap-10. The valve Sis preferably in the formiof-a sector,,andisfprovided with an a-rcual slot 14 so as to form a spring arm carryingvalve face 15, which is designed to cut off the entrance of water fromthe bypass to the pressure chamber. This valve 8 has a radial face whichcarries from the pressure chamber whenthe by-pass is open, xandaforopening such outlet when the by-pass is closed. I have shown the outletfrom the water' chamber as consisting of a pipelF, held in place by aplug and which may be connected to the bowl.

' As shown in Fig. 2, when valve 8 is moved to uncover the by-pass, theoutlet through pipe 17 is closed by the radial portion of the valve.lWhen the latter is in this position pressure will build up and effectthe seating of the main valve against the incomlVh'en the control valveis moved into the position shown in Fig. 3, the by-pass is cut off, andthe pressureis relieved by uncovering pipe 17, permitting the main valveto be automatically unseated. Normally, the operating handle 12 occupiesa horizontal position, as indicated in Fig. 2. When raised to permit theoperation of the fiusher, it will.

promptly return to its normal position by gravity, and in so doing willmove the control valve to close the outlet from the pressure chamber,and open the inlet thereto through the by-pass. l/Vithin the by-pass 4cI locate a cook 20 by adjusting which the quantity of water allowed toflow through the bypass for seating the main valve may be controlled.and by reason thereof also the time required for the main valve toreturn to its seat.

The advantages of my invention will be apparent to those skilled in theart. It will be noted that in my present flushing device the use ofsprings is unnecessary; that the device is composed of comparatively fewparts, and hence not liable to readily get out of order; it will closewithout jar or shock; is noiseless in operation; and the main valvebeing free to turn on its own axis will wear longer than one moving onfixed lines, and having a double seat the wear is reduced onehalf ofwhat it would be with but a single seat. a

I claim as my invention:

1. A flushing device comprising a casing having an inlet, an outlet, apressure cham- Patented Aug. 18, 1914.

adisk 16' of anysmtable material for closing the outlet ber, chamberwith the inlet side of the casing, a main valve fitted in said chamberand designed to cut off communication between the inlet and outlet, saidvalve having a centrally extended lug which is designed to fit in saidinlet to restrict-the outflow when the valve is opened, said pressurechamber having a relief outlet on the same plane as, but away from theentrance of, said by-pass into said pressure chamber, a disk-like rotaryvalve having port controlling faces in parallelism with the axis of saidvalve for normally closing the outlet of the pressure chamber andopening communication between the latter and said by-pass, and anoperating handle for rotating said valve to uncover said latter outletand close communication with said by-pass.

2. A flushing device comprising a casing having an inlet, an outlet, apressure cham ber, and a by-pass connecting said pressure chamberwiththe inlet side of the casing, a main valve fitted in said chamber,and designed to' cut off communication between the inlet and outlet,said pressure chamber having a relief outlet, a rotary valve having aspring arm for closing said by-pass, and also having a radial portionfor closing the outlet from the pressure chamber, which outlet is atright angles to the pressure chamber, and

and a by-pass connecting said pressure an operating handle for movingsaid control valve. v

3. A flushing devicecomprising a casing having an inlet, an outlet, apressure chamber, and a bypass connecting said pressure chamber with theinlet side of the easing, said pressure chamber having an outlet, a mainvalve of cylindrical formation capable of moving longitudinally in saidpressure chamber and having a reduced portion,

said valve being capable of turning on its 7 axis, a control valve inthe form of a sector having two port-controlling faces, one facecontrolling said by-pass, and the other the outlet from the pressurechamber.

4:. In a flushing device having a pressure chamber, a port leading intosaid pressure chamber, and an outlet pipe leading from the pressurechamber at right angles thereto,

a valve in the form of a sector having a spring arm, the end of which isdesigned to extend over said by-pass, said valve also having a radialface for closing said outlet pipe.

In testimony whereof, I have signed this specification in the presenceof two subscribing witnesses.
